Definition
  1. Noun:
    • Equality of extension or duration: The state or condition of having exactly the same spatial extent, scope, or length of time.
Usage
  • The word "coextension" is a formal, often philosophical or technical term. It is used to describe a precise relationship where two or more things share identical boundaries in space or time.
  • It is typically used in academic, logical, or scientific contexts, such as in metaphysics, geometry, or linguistics.
Examples
  • Noun:
    • In logic, the coextension of two concepts means their sets of referents are identical.
    • The coextension of the lease and the rental agreement prevented any legal gaps in occupancy.
    • Philosophers debate whether the mind and the brain have perfect coextension.
Advanced Usage
  • "Coextension of predicates": In logic and semantics, this refers to two predicates that apply to exactly the same set of objects.
    • The predicates "has a heart" and "has a kidney" are often cited as an example of coextension in biological organisms, though not necessarily conceptual identity.
Variants and Related Words
  • Coextensive (adj): Having the same spatial or temporal extent; extending equally over the same area or duration.
    • The jurisdiction of the two agencies is coextensive.
Synonyms
  • Congruence (in the context of spatial equality)
  • Simultaneity (in the context of temporal equality)
  • Equivalence in extent
Notes
  • "Coextension" is distinct from simple similarity or overlap. It implies a complete and total equality in the scope, range, or duration being compared.
  • It is often contrasted with terms like "extension" (the scope of something) and "intension" (the inherent meaning or definition of something).
